lirsrv-e etnereo I usually;provided adjacent one end thereof andsecuredin position by a bolt extending through I the shuttle andthreading block and clamping the block inposition between the front andrear walls thereof. The wood of the shuttle 'body is relatively'thin atthe front wall and the clamping pressure exerted on the head of the boltby the.

nut is often times sumcient to cause the wood at this point to split orbreak and on some occasions the head of the bolt may even be pulledthrough the front wall.

In order to avoid such a condition, it has, heretofore, been proposed toreinforce the wood adjacent to the side delivery eye by inserting pegsof wood, metal, or other suitable material. These pegs have beensatisfactory for varying periods but under most conditions these pegsloosen after the shuttle has been used for a period and thus are nolonger effective to prevent splitting or breaking of the wood.

One object of the present invention is to pro-- vide a constructionwhereby the above mentioned difficulties may be overcome- To this endand. in accordance with one feature of the invention, a'peg formed ofsuitable material such, for example, as vulcanized fibre, is insertedinto the bodyof the .block adjacent to the side delivery eye in aposition where the peg will be engaged by and locked in. position .bythe clamping means. In the illustrated construction, two vulcanizedfibre pins are used, both pins being cut away to a certain extent whenthe front wall is counterbored to receive the head of the clamping bolt.

-Thus, each pin'is engaged by the head of the [bolt and is preventedfrom loosening and pullin which the present invention is embodied;

In present shuttles, athreading block is Fig. 3: is aisectional viewtaken along the line III --III of Fig. 2-

direction and ,a pinh22 secured in the threading block|6,'forrnif1g"abearing member'for the running bearing when the shuttleis picked in the other direction. The shuttle eye I6 is maintained andclamped in the cavity I4 by a bolt 24 extending through the front andrear walls 26, 28 respectively, of the cavity l4. The bolt is providedat one end with the usual head 30 and at its other end with a nut 32.nut 32 are located in counterbored openings 34, 36, respectively. Theconstruction described above is old and well known in the art and neednot be described in further detail herein.

As shown best in Fig. 3, the front wall 26 is drilled to receive postsor pegs 38, 40 formed of vulcanized fiber or other suitable material.The holes for the pegs are formed before the various cuts are made toreceive the threading block [6 and the side delivery eye. The holes forthe pegs are drilled from the bottom of the shuttle body and. terminatejust above the hole for receiving the bolt 24. that the counterboredhole 34 for the head 30 of the bolt terminates in the upper end portionof said peg 38 so that a portion of the head 30 seats in the cut awayportion 42 of the peg 38. The peg 40 is substantially smaller indiameter than the peg 38 and is located close enough to the hold for thebolt 24 so that a portion of the head 30 will seat against a shelf 44thereon formed when the hole 34 is counterbored.

The pegs or posts 38, 40 fit tightly into their respective holes and inaddition are coated with glue to insure that they will stay in position.The pegs reinforce and strengthen the front wall 26 and preventit fromsplitting or :breaking during use. cut away portions of the pegs whichform an effective seat for said head and prevents the head 30 from beingpulled through the wood' when clamping pressure is applied by tighteningthe nut 32. The head 30 also prevents the pins from 7 movinglongitudinally or'from turning so that tially eliminated.

Thehead 30 and the The peg or post 38 is so located 7 The head 30 of thebolt 24 fits into the When the opening is formed in the front wall 26for the side deliveryeye l8 and during subsequent finishing operations,the wood adjacent to the peg 38 is cut away to receive the threadingblock Hi. The peg 38 is also cut away at 48 to form a surface over whichthe running filling passes during operation of the shuttle. The fiberpeg 38 forms a smooth even surface free from projecting fibers orsplinters which would injure the running filling. The peg 38 thus notonly provides a seat for the head 30 of the bolt 24 and reinforces theshuttle body but also provides a smooth surface over which the fillingis guided as it passes from the side delivery eye.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent of the United States is:

said threading block in position, said shuttle body being counterboredbetween said pins to receive the head of said bolt and to provide a seatfor said head on each of said pins.

3. A shuttle comprising a shuttle body having a recess for receiving afilling carrier, a cavity communicating with said recess for receiving athreading block, and a side delivery eye in th@ 7 front wall of saidshuttle body and communicat- 1. A shuttle comprising a shuttle bodyhaving a I recess for receiving a filling carrier, a cavity com-'through said threading block to hold said threading block, in position,said pins each being provided with a shelf forming a seat for the headof said bolt.

2. A shuttle comprising a shuttle body having a ing with said cavity, apin vertically mounted in the front wall of said shuttle body andforming at least a portion of one side of said delivery eye, a secondpin parallel to said firstpin and located inwardly therefrom, each ofsaid pins having a cut away portion defining a flat seat, and a clampingbolt passing through a hole formed between said pins and through saidthreading block to hold said threading block in position, said flatseats on saidpins being engaged by the head of said bolt and preventingradial and axial movement of said pins.
